Comparative Study of the Application of Chelating Resins for Rare Earth Recovery [PDF]

open access: yes, 2017
The adsorption properties of chelating ion exchange resins containing mixed sulfonic/phosphonic (SP), aminophosphonic (AP) or iminodiacetic (IDA) acid functional groups were investigated towards the rare earth elements (REE). The aim of this work was to

Implementation of Ion Exchange Processes for Carbon Dioxide Mineralization Using Industrial Waste Streams

open access: yesFrontiers in Energy Research, 2020
Sequestration of CO2 within stable mineral carbonates (e.g., CaCO3) represents an attractive emission reduction strategy because it offers a leakage-free alternative to geological storage of CO2 in an environmentally benign form.

Water, electricity and ion exchange; how Hamish Small sustained the evolution of ion chromatography

open access: yesHeliyon, 2021
Since the development of synthetic ion exchange resins in 1935, the electrochemical properties of these unique materials have intrigued researchers. In 1951, Hamish Small was introduced to synthetic ion exchange resin when he studied the electromigration

Catalytic Dehydration of Fructose to 5-Hydroxymethylfurfural (HMF) in Low-Boiling Solvent Hexafluoroisopropanol (HFIP)

open access: yesMolecules, 2018
A mixture of hexafluoroisopropanol (HFIP) and water was used as a new and unknown monophasic reaction solvent for fructose dehydration in order to produce HMF. HFIP is a low-boiling fluorous alcohol (b.p. 58 °C).
